C represents a sectional view ot' a portion of acask or reservoir for containing gaseous liquids, and havinga-..metallic lining, c. D is the ordinary tap, through which said casksare filled and discharged, and consists ot' a short pipe ex- When thecap is removed to attach the draftpipe a wast'a'ge of gas and liquid isunavoidable.'

To adapt the invention to the ordinary tap, described above, the tube Ais enlarged and threaded with afem'ale screw to titover the tap D, andthe tube A is threaded to receive the cap E.

If, now, the device is put in place, as shown at Figs. 1 and 2, then thecap E removed and the cork-key B turned to open the passage, the Caskmay be filled. When filled the cocks may be closed and then the cap Escrewed on, when i-t may be handled or shipped, as desired.

With the key B turned to'close the passage through the cock A, the cap Emay be removed and the draft-piping attached without leakage of gas orliquid; then the key being turned to open the passage the iiow vwill beuninterl rupted; Y

In this device the lower tube is provided with a flange,D', and a short threaded pipe, extending through the Cask-head, and issecured to the cask as described, in regard to the tap aforesaid. A cap,E, is also screwed on the top or upper tube of the cock A.

The operation inr filling the cask, and in coupling the draft-pipe tothe cock, is thc same as hereinbefore described. l

I claim- The cock A, having the internally-screwthreaded tube A at oneend and the externally-threaded tube A at the other, in combination withthe iiauged tap-piece D and removable cap E, substantially as and forthe pur- -pose specied.
